Here you will find measuring devices for static and alternating electric and magnetic fields.
In 1993 we presented with the Fieldmeter FM6 one of the first reliable, modern and precise measuring devices for field strength ("Ökotest" winner 06/1996).
Today the Fieldmeter FM10 is a basic measuring device with a comprehensive range of different measuring probes, an universal solution for measuring fields.
An example is the electric field probe EPL3 for measuring isotropic, potential-free electric alternating fields.
